作者： SUN Wu1, LI Sen2 (1. department of geography, South china normal {4., Guangzhou 510631, china 2. department of geography, Foshan {4., Foshan 52800, china)

From the analysis on the problem of selection, data acquisition, quantification and accuracy check in the indicators to desertification degree both at home and abroad, one might conclude that in the existing assessment of desertification degree there is a prevailing tendency which is the substitution of absolute landscape for relative land degradation, namely, assessment of desertification degree is that of absolute landscape state to some extent. As a result the reassessment accuracy of desertification scope, damaging degree and control effect are affected. The regaining and establishment of the initial and final ecological datum level of land degradation are the prerequisite to the establishment of normal scientific indicator system. From the viewpoint of this three design principles of indicators to the desertification degree are put forward: the zonal principle of indicator systems decided by the ecological datum level corresponding to their bioclimatic zones, the hierarchical principle of indicator systems decided by different spatial scales and the resolutions of different sensors and principle of landscape types based on the 3S as core-indicator.

初唐制定的道先佛后政策 ,使得魏晋以来的佛道之争更为激烈。由于没有最高统治者的支持与肯定 ,佛教始终处于劣势地位。虽然如此 ,佛教在唐代还是发展到了鼎盛时期。这除了其自身的教义易为大众接受以及玄奘等许多佛学志士的不懈努力之外 ,唐太宗为玄奘所译诸经写的总序《大唐三藏圣教序》与两种不同字体的“圣教序碑”亦功不可没。

Heart valve diseases threaten human health. One reliable way to save lives of such patients is to replace the pathologically changed heart valves by artificial ones. Over 2 million patients have received LTI-carbon heart valve’s implantation. However, the thrombosis after the implantation is one of the difficulties that need to be solved. In order to improve the blood compatibility and security of mechanical heart valves, ion beam technology was used to modify the surface properties of the materials. The investigation results have been summarized in this paper.

The asymptotic behavior of solutions of a model for competition between two microorganisms in the chemostat is studied. The model incorporates time delays that allow for cellular components of each competing species to be structured to include unassimilated or stored nutrient and allow uptake functions to be nonmonotone. By introducing two auxiliary functions and using fluctuation lemma, it is shown that at most one competitor survives, and the substrate and the surviving competitor (if one exists), approach limiting values. Our results indicate this kind of time delays do not influence the competitive outcome except for a critical case. The main results of S. F. Ellermeyer[1] are improved on and extended.

关键词： Chemostat competition time delays global dynamics.
